To all whom it may concern:

Be it known that I, J OSEF HREN, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented new and useful Improvements in Applying Strips to Books,Pamphlets, Pads, and the Like, of which the following is aspecification.

By means of this invention a strip or tape can be applied to a block orpad or to the back of a book or pamphlet. The strip can be ofv anysuitable material, such as muslin, paper, or the like. Such strip ortape having been rendered adhesive is made to conform and adhere to thearticle and the strip having been trimmed or cut the backed or tapedarticle is delivered.

The invention resides in the novel features of construction set forth inthe following specification and claims and illustrated in the annexeddrawings, in which Figure 1 shows a plan view of a machine or deviceembodying this invention. Fig. 2 SllOWS a side elevation of Fig. 1. Fig.3 is a section along 00 m, Fig. 1. Fig. A is a section along 3 y,Fig. 1. Fig. 5 is a view like Fig. 4 with parts in a different position.Fig.6 is a plan view of a knife or trimmer for severing a tape or strip.Fig. 7 is a section along .2 2, Fig. 6. Fig. 8 is a sectional view ofantifriction bearing or rollers for a belt. Fig. 9 shows a tape-former.Fig. 10 is an edge view of Fig. 9. Fig. 11 shows a roller made yieldingor pneumatic, so as to conform to the shape or back of a book or articlewhen pressing a strip thereagainst. Fig. 12 shows an adjusting-screw fora feeding sprocket or chain. Fig. 13 shows a round book-back when tapedor provided with a strip. Fig. 14 shows a square back taped or providedwith a strip.

In the drawings are shown feed-rollers a for feeding or moving a book 6or the like, to the back of which a strip or tape 0 is to be applied bybrushes (Z. This strip may be a previously-gummed strip which has beenmoistened or a freshly-gummed strip applied before the paste has dried.A shaft 6 by gears f engages gears g of two oppositely-placed pairs ofrollers (0. These rollers are made in form of sprocket or chain wheels,about which run belts or chains 72/. The book being grasped between theupper and lower chains is carried along and the strip or tape 0 applied,as presently explained. To prevent defacing or denting by the chains,the latter may have a soft or suitable covering of leather or otherprotecting or contact material.

The space between the feeding devices or chains can be varied forvarying thicknesses of objects. One of the gears f feathers on shaft 0,so that as this chain or feeder is set from or toward the other theshaft retains its gear connection. In the drawings the upper chain orfeeding mechanism is shown adjustable. This adjustment of this part ofthe feeding mechanism is attained by tapped sleeves i, Figs. 11 and 12,made to adjust or move uniformly by sprocket-wheels 7c, Figs. 2 and L,and connection or chain Z. One of the sleeves is shown with a handle orhandwheel at. (Shown on larger scale in Fig. 12.) As these screws orsleeves are turned one way or another in arms or brackets a the screws0, which support or form part of the block or hearing 0 of one set ofrollers or sprockets a, are adjusted to or from the other set ofsprockets or rollers. The arms or brackets n are supported by posts 36,which rise from the table or feed-board or are supported on the frame orlegs 37. This table or feedboard'3 t can be leveled or adjusted toproper position by means of a leg 35, Fig. 2, shown with telescoping oradjustable sections. The upper chain being pressed by the book againstthe block 0 and the lower chain lying on the feed-table, such chainswill be kept alined or parallel, so as to secure an extended grip alongthe flat faces or sides of a book cover or pad.

The brushes cl have their shafts supported by brackets 19 and arerotated by gear 9, engaging gear 0 on shafts s. The gear 9' of the brushon movable support 0', adjusted by screw 0, feathers to accompany theadjustment the same as the feathering-gear f. The shaft sis rotated bychain or connection 6, extending to shaft 0. The brushes (Z are placedat an angle to the back of the book and rotate so as to brush or smooththe tape or strip to the sides or faces of the book or article.

The strip is shown pressed against the bookback by aroller 38, which canbe more or less yielding to conform or make the strip conform to thebook-back. A pneumatic or inflated roller, as shown in Fig. 11, has beentried and found to answer; but of course a brush-roller or othersuitable device can be used withoutdeparting from the invention. Y

A tape-former was also applied to a device built according tothisinvention. Such tapeformer was constructed of blades 39, Figs. 1, 2,9, and 10, in a frame 40. Pivoted or swing- IIO ing at 41 and pressed bysprings 42 these blades or thin metal leaves press against the back ofthe book or article and also lap somewhat over the sides or covers. Theblades have each an edge facing the book or article being backed.Swinging independently on pivot 41 and having each its individual springpressing it toward the book such blades can clasp or conform a tape orstrip in suitable manner.

Presser-belts 43, Figs. 7 and 8, are also shown running over guides orantifrictionrollers. These belts on antifriction-bearings aid in holdingor pressing the strip to the book passing therebetween. In addition tothese belts are shown presser-springs 45, which aid in pressing thestrip or causing it to lie or adhere smoothly to the article. The upperone of the presser-belts 43 and presser-springs 45 are carried by thesupport 0, carried by screw 0, to be adjustable therewith.

The books or articles coming from the feedboard are spaced by theoperator placing a finger between each pair of books as they are movedalong or by other suitable means. so that the continuous tape can besevered between such books, as presently explained.

The tape coming from a roll or supply is led over a roller 46 and thenguided by a roller or stud 47, Fig. 2, at right angle to the precedingone, so as to be given a twist or present its adhesive side to thearticle. The roller 47 can have collars 49 adjustably arranged toaccommodate varying width of strips. A takeofl' or delivery belt 50,suitably actuated, can carry off the completed or backed articles to adelivery-point.

In Figs. 4 and 12 a spring 01' flat spring disk 51 is shown between thebracket a and the support oor its sprocket-wheel 7;. Such spring allowsa yield for variations such as occur in the thickness of some pads orbooks. Such yield has been found to be of ad vantage in a machine builtaccording to this invention.

To .aid or keep the books to proper alinement or register relative tothe tape or strip, a guide or gage can be applied. A practical gage isobtained by lingers 52, Fig. 1, pressed by springs 53 and mounted orpivoted on a gage-bar 54, which can be suitably adjusted. A bolt orscrew 55 of a screw-and-slot connection allows adjustment.

The knife is shown at Figs. 4, 5, and 7. The spring 8, Fig. 6, foractuating or rotating this knife-blade 7 is connected to shaft 9 by afriction-sleeve 10. Said sleeve has loosely mounted thereinfriction-plugs 10 which are held by a spring-band 10 in contact with theshaft 9 or with the enlargement at one end of said shaft, said yieldingengagement causing-the requisite frictional contact of such plugs withthe shaft to enable the springs 8 to be wound. The shaft 9 is rotated bygear connection 11 and 12, Fig. 2, actuated by shaft 1;. After thespring 8 has been wound to a certain tension the shaft 9 slips orrotates and driving means for the brushes.

in the friction-block 10; but the knife is ready to be spunabout by thespring 8 as soon as the detent or escapement 14, Fig. 4, is released.

The detent or lever has one arm held by spring 15 up above the level oftable 34, Fig. 4, on which the book comes along. When the book depressesthis lever or detent-arm, Fig. 5, the outer portion of the arm clearsone of the studs 16, but comes into the path of the other, as thesestuds are sufficiently eccentric on disk 17. The spring can now snap orswing the knife about one-half of a turn, or from the position in Fig. 4to that in Fig. 5. When the book has passed, the spring 15 returnsdetent to the position shown in Fig. 4 and the knife swings to rest atthe starting position, with a stud 16 at rest against the detent untilthe latter is again actuated by a book pressing thereagainst.
